蒙古国农场与天津郭村耕层土壤性质及微生物数量分布初探

On the Properties and Microorganism Contribution of the Soils from Mongolia and the Guocun Villege in Tianjin

分别对蒙古国第二农场和天津郭村小麦及黄瓜耕层土样的基本性质(酸碱性、含水率、全氮、速效磷、速效钾及有机质)与微生物的数量分布进行测定并比较.结果表明,天津郭村土样仅全氮含量低于蒙古国土样,其余指标均不同程度地高于蒙古国土样.这些结果可为提高蒙古国土壤肥力、改善土壤生态环境提供理论依据.

The contents of total nitrogen, available phosphorus, available potassium and organic matter, quantity of the soil microorganisms as well as the pH and water content of the soils from Mongolian and the Guocun villege in Tianjin are determined separately. The results indicate that the contents of total nitrogen of Guocun＇s soil sample is lower than that of Mongolia soil sample, but organic matter, the contents of available phosphorus and available potassium of Guocun＇s soil sample is higher, so are the content of fungi, actinomycetes and bacteria of Guocun＇s soil sample.
